Using Objectify For retrieving from Datastore- Error :Did you forget to inherit required module

I am using Objectify for retrieving data From datastore in GWT,But i get the Following Error :

[ERROR] No source code is available for type com.logins.entity.experts; did you forget to inherit a required module?

I have Client->entity->Server and i did define the RPC properly with RemoteServicePath. i intiaized the Rpc in client side

final findexpertAsync finexp=(findexpertAsync)GWT.create(findexpert.class);

GWT compiler throws Error at the method i call,

finexp.expert(expnam, new AsyncCallback<ArrayList<experts>>()

Note:

1) findexpert and FindexpertAsync are the RPC interface which has a method for retriving data from datastore 2)com.logins.entity.experts:experts is a server class.

Any guesses where i am going wrong ?

Solution

  • All classes directly or indirectly referenced from the client must be part of the client source path. You can't access server-only code from GWT. In this case, class "experts" needs to be part of the GWT-compiled client code.

    Also: You should capitalize Java class names.
